Also interesting to note, McAfee identifies eEye's free RPC scanning tool as an "exploit/trojan" because of a (presumed) faulty check. That or they are using their product's market share to effectively shut out their competitors who offer free tools to help secure networks.

McAfee Antivirus Tool Blocks Internet Access,3959,1212162,00.asp

Some Network Associates Inc. customers are up in arms over an update
for one of the company's antivirus products that is preventing them
from accessing the Internet.

The problem is caused by an update for McAfee VirusScan Professional
7.0, the company's flagship enterprise antivirus application. When
update 7.03 is installed on some machines running Windows 2000 or
Windows XP, it prevents the PCs from connecting to the Internet after
the suggested reboot. The problem seems to be affecting customers who
upgraded from 7.02 to 7.03.

McAfee has pulled the update from its download servers and is
performing quality checks on it, according to information on the
company's Web site, but has not provided customers with any
instructions on how to fix affected machines.

"I am so angry with these people it's palpable. I write software and
cannot believe they released a patch before thoroughly testing it,"
said Michael Shohoney, a VirusScan user who said his PC was down for
more than six hours before he was able to restore the Internet

A spokeswoman at NAI, based in Santa Clara, Calif., said she was
unaware of the problem and would look into it.

Some users report that uninstalling the troublesome patch and
reverting to the last known good version of VirusScan restores their
Internet connectivity. However, others say this hasn't worked for

A McAfee technical support representative writing in the site's help
forums said that the company believes the problem lies in a DLL that
controls the Hostile Activity Watch Kernel (HAWK), a feature that
looks for malicious and "virus-like" behavior.
